Seizures

Generalized seizures involve both hemispheres from onset.
Partial seizures are restricted to one hemisphere; complex partial seizures focus on a specific brain area.
Status epilepticus is a series of seizures without recovery, risking irreversible brain damage primarily due to airway maintenance issues.

Alzheimer Disease

Associated with structural brain changes, particularly amyloid plaques and neurofibrillary tangles.
Diagnosis requires ruling out other dementia causes; brain biopsy is not necessary.
Increased protein in lumbar puncture is not indicative of Alzheimer dementia.

Parkinson Disease

Results from dopamine deficiency in the substantia nigra; not linked to CNS demyelination or pyramidal nerve tract lesions.
Treatment focuses on increasing dopamine in the CNS; anticholinergics are utilized for symptom management.
Classic symptoms include a rest tremor and skeletal muscle rigidity; akinesia and stiffness in movement follow.

Spinal Shock and Autonomic Dysreflexia

Spinal shock includes absent spinal reflexes below injury level; paralysis and loss of sensation occur.
After spinal shock, autonomic dysreflexia can develop, characterized by hypertension, bradycardia, and upper body flushing.

Seizure Types

Absence seizures (petite mal) are brief and typically occur in children, characterized by staring spells lasting seconds.
Initial treatment for seizures prioritizes airway maintenance to prevent injury, with anticonvulsants following for specific seizure types.

Orthostatic Hypotension

Common in Parkinson disease due to autonomic nervous system involvement; not typically associated with Alzheimer disease, multiple sclerosis, or amyotrophic lateral sclerosis.

Acquired Parkinsonism

Common causes include history of infections, intoxication, or trauma; differs from idiopathic parkinsonism, which has a gradual onset related to dopaminergic neuron degeneration.
